After finding out that she had to be naked in front of Leonardo DiCaprio, Kate Winslet decided to break the ice, and when they first met, she flashed him

The hands seen sketching Rose are not Leonardo DiCaprio's, but director James Cameron's. In post-production, Cameron, who is left-handed, mirror-imaged the sketching shots so the artist would appear to be right-handed, like DiCaprio.

At $200 million, the movie cost more than the Titanic itself. The cost to construct the ship in 1910-1912 was £1.5 million, equivalent to $7.5 million at the time and about $120 to $150 million in 1997 dollars

A recent investigation showed that if Titanic had hit the iceberg head-on, she would have survived. Though damaged she would not have sunk and would have reached New York -- maybe a day or two late

The post-sinking scenes were shot in a 350,000 gallon tank where the frozen corpses were created by applying a powder on the actors that then crystallized when exposed to water. Wax was applied to hair and clothes to create a wet look

Kate Winslet was one of the few actors who didn't want to wear a wetsuit during the water scenes. As a result, she got pneumonia, and nearly quit the production. However, James Cameron persuaded her to stay.

Many of the "core extras" used for the movie took on characteristics of actual survivors. One scene where two little girls are loaded onto a lifeboat and the man says, "It's only for a little while" is based on testimony from one of the girls who survived. The man also says in the scene, "Hold Mommy's hand and be a good little girl." According to survivor Eva Hart, these were the last words her father said to her before the lifeboat she was in was lowered

The last remaining survivor of the Titanic was Millvina Dean born 2 Feb 1912. She died 31st May 2009 aged 97. She never married or had children
